The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

Mark Jo, MD appears in the CMS NPPES registry as a Orthopaedic Trauma Physician provider holding MD credentials at 10 CONGRESS ST, Pasadena, CA, 91105, with a listed phone of (626) 795-0282. NPI 1689974255 was issued on 10/28/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Jo most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 421 prescription claims written by this provider, covering 161 Medicare beneficiaries and totaling roughly $16K in drug spend, split 5% brand-name and 95% generic by claim count, with an opioid prescribing rate of 17.1%. These figures capture only Medicare Part D, commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 75/100 for the 2023 performance year, compared with the national average of 83.1.

Orthopaedic Trauma Physician is a narrow specialty nationwide, with 715 enrolled providers across 51 states and an average of 160 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist, always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.

  • Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
  • Check the active license and any disciplinary history with the California medical board, federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Orthopaedic Trauma Physician peer on Medicare volume and prescribing patterns. Compare providers
